"The installation of a muffler for cars and motorcycles will enable people to find ease in a lively city." Wang Zhenwu said that in the current power machinery, almost all of the electric machinery, such as internal combustion Engine power units, cars and motorcycles. Both are driven by internal combustion engines. "The noise generated by the internal combustion engine is a major part of urban noise. My invention is to make this part of the noise disappear."
According to reports, Wang Zhenwu invented the "internal combustion engine muffler" full name is called the internal combustion engine exhaust phase shifting differential muffler, has obtained national patents. It is understood that the environmental pollution of internal combustion engines includes two aspects: one is air pollution, and the other is noise pollution. The source of the two pollutions mainly produces the exhaust process during the operation of the internal combustion engine. Exhaust muffler devices are installed on various internal combustion engine driven vehicles and other internal combustion engine devices. However, the biggest disadvantage of these muffler devices is that the structure is complicated and the exhaust has a certain resistance. This results in an unsatisfactory noise reduction effect and increases exhaust pollution.
The invention of Wang Zhenwu aims at avoiding the shortcomings of the above two aspects, and phase shifting, differentiating and combining the exhaust sound waves of the internal combustion engine to convert a high-amplitude narrow-pulse sound wave into a plurality of small-amplitude narrow-pulse sound waves that are mutually staggered. Thereby, the noise flow of the pulse amplitude is reduced to the sensory stimulation of the human ear. The most distinctive is that the "muffler" is simple in structure, small in size, without any baffles and unnecessary conduits, which makes the noise reduction effect significantly improved, and at the same time reduces the exhaust pollution of the car.
The "internal combustion engine muffler" invented by Lanzhou Wang Zhenwu
"The noise pollution caused by cars and motorcycles in the city strongly stimulates people's hearing and disturbs people's minds. If there is a muffler that can make the annoying noise 'decrease' to the greatest extent, it is the original intention of my invention." Recently, Lanzhou's Wang Zhenwu showed his new invention to the group.
